My husband and I stayed 3 nights at Nattavut's flat. Nattavut was really helpful and picked us up from the airport when we arrived. He was also quick to respond to any questions we had beforehand.
The flat was nice and exactly as shown with access to a pool on the 18th floor.
Ari is a great area to stay in with lots of cafes and places to eat. There's a big supermarket next to Ari station which is only a few minutes walk from the flat.
The flat and the area was perfect for us. We have been in Bangkok before where we saw most of the tourist sights, so it was great to stay in another kind of area. It might be a bit out of the way if one wants to lots of sightseeing.
